摘要： A sheet feeder feeds sheets separated from a stack to a feed head which is translatable toward take away nip rolls. The sheets are separated from the stack by fluffers and acquired by an acquisition surface of the feed head which is in communication with a vacuum pressure. An air knife is used, in conjunction with a corrugation surface, to separate any secondarily acquired sheets from the acquisition surface. The time for acquiring the sheet is determined from the opening of a vacuum valve in communication with the feed head to the acquiring of the sheet by the acquisition surface. The time for acquiring the sheets is dependent on the sheet characteristics. A controller adjusts the pressure to the fluffers, air knife and the vacuum pressure to control the sheet acquisition time based on the sheet acquisition times of a predetermined number of previously successfully fed sheets and a standard deviation as compared to a table of predetermined sheet acquisition times and standard deviations for the particular sheet characteristics.

摘要： A stack height assembly consisting of two transmissive sensors and two flags, the stack height of a feeder module can be set to three different levels depending on the weight of the media. This “optimization” of the stack height to address the media's failure mode results in increased latitude. When feeding lightweight media, the stack height is set larger in order to increase the gap to the feedhead. This allows more room for separation of the media using fluffer jets. This increased gap also reduces the chances that the un-acquired media will be fluffed into contact with the acquisition surface and subsequently be shingle fed into the take away roll due to the friction between sheets. When feeding heavyweight media the stack height will be set smaller. This reduces the gap to the feedhead and reduces the time required to acquire.
摘要翻译： 由两个透射传感器和两个标志组成的堆叠高度组件，可以根据介质的重量将馈送器模块的堆叠高度设置为三个不同的等级。 堆栈高度的这种“优化”来解决媒体的故障模式导致纬度的增加。 当喂入轻质介质时，堆叠高度设置得更大，以增加与进料头的间隙。 这样就可以利用蓬松的喷气式空间来分离介质。 这种增加的间隙也降低了未采集的介质将被卷起与采集表面接触的机会，并且随后由于纸张之间的摩擦而被带入进料辊。 喂食重量级媒体时，堆叠高度会变小。 这减少了进给头的间隙，并缩短了获取所需的时间。

摘要： A sheet stacking tray system for stacking different sizes of copy sheets on a stack supporting tray to be fed upstream to a reproduction apparatus for printing, on which tray the stack is registered against a side registration edge. An upstanding stack rear edge guide is track mounted for movement at an angle to that side registration edge to provide a large repositioning movement in the upstream direction together with automatic lateral movement toward or away from that side registration edge, so as to engage the rear edge of a stack of larger sheets further from the registration edge, more centrally of the downstream edge of those sheets, and to engage smaller sheets closer to the registration edge and thus more towards their centers. Two independent upstanding stack side edge guides may be repositionable towards the registration edge independently of, and not overlapping, any position of the angulary moving rear edge guide. The rear edge guide may be linearly track mounted at approximately 18 degrees to the registration edge. All three stack edge guides may extend through and move along separate elongated apertures in the tray. The downstream edge guide may be repositionable substantially closer to the registration edge than the upstream side edge guide due to the angular track of the rear side guide.

摘要： A feed apparatus which combines a slider crank feed head drive system and cam actuated stack height sensing system to form a new combined shuttle feeder. The new feed head drive includes the replacement of a solenoid driven feed head with a more reliable stepper driven twin slider crank drive. Included in the slider crank drive for the feed head is an integral cam as part of the crank arm mounted to the motor shaft. This cam is designed drives a stack height sensor to drop and lift the stack height sensing arm to sense stack height after the sheet trail edge has passed the point of arm contact with the stack. The cam also provides a “service mode” position for the stack height arm which lifts it out of the way of the paper supply when it is opening. The cam dwells in a neutral home position during the rest of the drive out and return motion of the feed head.

摘要： An adjustable force driving nip assembly for use in a sheet transport system of a document creating apparatus has a plurality of adjustable force driving nips aligned and spaced transversely across the sheet travelling path of the sheet transport system. Each driving nip has a spring biased idler roller mounted on a cam follower and mated with a driven roller. The spring bias produces a normal force for the idler roller that urges the idler roller against the driven roller. A stepper motor is adapted to interact concurrently with the cam followers and, upon actuation, vary the force of the spring thus adjusting the normal force of the idler rollers. A controller actuates the stepper motor in response to sheet media data entered into a control panel of the document creating apparatus by an end user, thereby automatically adjusting the normal force of the idler rollers to prevent sheet marking.

摘要： A dual path, single reversing roll inverter driven by a single actuator includes a single reversing roller with two, diametrically opposed idler rollers. The configuration of the reversing roller and idler rollers forms a first nip and a second nip that are alternately used to accept sequential sheets from a paper path. The first and second nips discharge the sheets into respective first and second inverting paths. A method for inverting sheets using the dual path, single reversing roll inverter includes rotating the roller in a first direction to direct a first sheet through the first nip. The roller is then rotated in a second direction opposite the first direction to direct the first sheet from the first nip and into the first inverting path and to simultaneously direct a second sheet into the second nip. A gate alternately directs the sequential sheets into the first and second nips.
